In what order are elements deleted in a queue?
Queue follows the FIFO (First – In – First Out) structure. According to its FIFO structure, element inserted first will also be removed first. In a queue, one end is always used to insert data (enqueue) and the other is used to delete data (dequeue), because queue is open at both its ends.
In which type of queue the insertion and deletion can occur from both ends?
Double ended Queue: Double Ended Queue is also a Queue data structure in which the insertion and deletion operations are performed at both the ends (front and rear).
Which of the following points to element is deleted next in stack?
Explanation: In stack data structure, elements are added one by one using push operation. Stack follows LIFO Principle i.e. Last In First Out(LIFO). A right parenthesis makes pop operation to delete the elements in stack till we get left parenthesis as top most element.

In which data structure elements can be inserted and deleted from only one end?
The queue is a linear data structure in which we can insert the element from one side of the list and delete the element from the other side of the list. The end of the list from where the elements are inserted is called the rear end and the end from where the elements are deleted is called the front end.
How elements are inserted and deleted in a circular queue?
Circular queues-Insertion and deletion operations in C++ Queue implements the FIFO mechanism i.e the element that is inserted first is also deleted first. Queue cane be one linear data structure. A circular queue is a type of queue in which the last position is connected to the first position to make a circle.
Which queue allows insertion and deletion from both the ends simple queue?
Double ended queue
Double ended queue allows insertion and deletion from both the ends i.e. elements can be added or removed from rear as well as front end.
Which of the following allows insertion and deletion at either end?
Explanation: In dequeuer, we can insert or delete elements from both the ends. In queue, we will follow first in first out principle for insertion and deletion of elements.
How will you delete an element from the stack?
remove(int index) method is used to remove an element from a Stack from a specific position or index. Parameters: This method accepts a mandatory parameter index is of integer data type and specifies the position of the element to be removed from the Stack.
In which order we can remove the elements in stack?
The order in which elements come off a stack gives rise to its alternative name, LIFO (last in, first out). Additionally, a peek operation may give access to the top without modifying the stack. The name “stack” for this type of structure comes from the analogy to a set of physical items stacked on top of each other.
Where does the insertion of next element take place in a queue?
The insertion of next element takes place at the array index. What is the reason for using a “circular queue” instead of a regular one? In a queue Insertion & Deletion take place at ________________. Stacks require dynamic memory, but queues do not. Queues use two ends of the structure; stacks use only one.
When does a normal queue get full in Java?
A normal queue, if implemented using an array of size MAX_SIZE, gets full when 8. If the elements “A”, “B”, “C” and “D” are placed in a queue and are deleted one at a time, in what order will they be removed? 9.
What is the difference between a queue and a stack?
Stacks require dynamic memory, but queues do not. Queues use two ends of the structure; stacks use only one. Stacks use two ends of the structure, queues use only one. If the numbers 5, 10, 3, 42 are enqueued onto a queue in that order, what does dequeue return? What is the term for inserting into a full queue known as?
How is a circular queue implemented?
A circular queue is implemented using an array of size 10. The array index starts with 0, front is 6, and rear is 9. The insertion of next element takes place at the array index. What is the reason for using a “circular queue” instead of a regular one?
